ViWhat is SASE?
SASE (Secure Access Service Edge) is the convergence of Wide Area Network (WAN) and network security services such as CASB, FWaaS, and Zero Trust, into a single service model distributed on a cloud platform.
SASE is a model that transforms security technologies and network connectivity into a single cloud platform to ensure scalable and fast security. The combination of networking and network security in SASE addresses the challenges of digital business transformation, edge computing, and workforce mobility.
The capabilities of SASE are provided as services based on entity identity, real-time contextual information, enterprise compliance/security policies, and continuous risk/reliability assessment throughout sessions. Entity identities can be linked to individuals, groups (branch offices), devices, applications, services, IoT systems, or edge computing locations.
Why is SASE important in today’s business environment?
When businesses use cloud computing technology to accelerate growth, a significant amount of data, user accounts, devices, applications, and services are accessed outside the company’s premises, meaning that the perimeter of the enterprise is no longer a physical location. Despite this change, network architectures are still designed so that data must pass through a separate network from the internal network and then return to the internal network. Regardless of their location, users still have to access the company’s network using expensive and inefficient technologies just to go back to the external network once again. This creates significant challenges in terms of service availability, user performance, and productivity.
Current network methods and technologies no longer provide the level of security and access control that digital organizations require. These organizations demand immediate, uninterrupted user access, regardless of their location. With the increasing number of remote users and software applications in the form of Software-as-a-Service (SaaS), data is moving from data centers to cloud services, and access traffic to public cloud services and branch offices is more significant than traffic returning to the data center. This has led to the need for a new approach to network security. However, these issues can be addressed through SASE.
Gartner’s SASE architecture is a solution for developing secure, policy-based access services, regardless of user location. In terms of security, SASE defines the convergence of data protection and threat prevention capabilities. This converged service is based on a common, low-latency footprint that is close to the user’s location, regardless of where they are.
Although SASE architectures cannot be implemented overnight, SASE is rapidly gaining momentum. Gartner predicts that “by 2024, at least 40% of enterprises will have explicit strategies for adopting SASE, up from under 1% at the end of 2018.” SASE has gained significant traction in the past 18 months, in part due to the Covid-19 pandemic forcing businesses to rely heavily on remote workforce.
The benefits of SASE
Mô hình bảo mật SASE có thể giThe SASE security model can help your organization in many ways:
- Flexibility: With a cloud-based infrastructure, you can deploy and deliver security services such as threat prevention, web filtering, sandboxing, DNS security, authentication information theft prevention, data loss prevention, and next-generation firewall policies.
- Cost saving: Instead of purchasing and managing multiple products, using a single platform will significantly reduce your IT costs and resources.
- Reduced complexity: You can simplify your IT infrastructure by minimizing the number of security products that your IT team has to manage, update, and maintain, consolidating your security system into a cloud-based network security service model.
- Increased performance: With a cloud-based infrastructure, you can easily connect to resources anywhere. Access to company applications, internet, and data is available globally.
- Zero Trust: The Zero Trust approach to the cloud eliminates assumptions of trust when users, devices, and applications connect. The SASE solution will provide comprehensive session protection, regardless of whether the user is accessing or disconnected from the company network.
- Threat prevention: With full content inspection capabilities integrated into the SASE solution, you will benefit from higher security levels and visibility in your network.
- Data protection: Implementing data protection policies within the SASE framework helps prevent unauthorized access and misuse of sensitive data.
